Ok so the heart, lungs and various other vital organs are placed in the ribcage to protect them. Why place the most vital organ in one of the most exposed places?

If it is a matter of heat then surely natural selection and evolution would have made it so that say blood conducted heat away from the enclosed brain?

It seems to me that if a horse and a donkey can mate to make a mule then a gorrilla and orangutang or chimpanzee and some other monkey should be able to as well. I'm not sure. And if they can what are the new animals called. Could the same thing apply to monkeys?

I know I can find these online but I always get so many different answers. I am hoping someone here can really help me - especially if there's a dentist somewhere online here :)!
1. I know I have to go to college for 4 years but do I have to go 2 or 4 years afterwards. I don't know if I want to study that long!
2. How much would I get paid in my FIRST year? I know that you get paid more the longer you stay!
4. What classes would I have to take in college? Please list all. Like a Math, a history, a foreign language, a biology. I already have some high school college dual credits that will help me.
5. I can't decide whether I want to be a HIGH SCHOOL HISTORY TEACHER or a DENTIST? ... Can you help me?
6. If I took Biology, Chemistry, and PHysics during high school - & next year my senior year I'm talking FORENSICS AND ZOOLOGY (although I should have taken AP Biology) would that be an type of preparation for me?
B/c I'm having alot of history classes to help decide if that's my major?!

Is there a direct reason why women like flowers and and other pretty trinkets? Or is it because receiving such trinkets is a representation of a male's spending power and therefore "success" as an individual? Has there been any research on this? I know that the question is a broad generalization, I hope you understand what I'm really asking though.
